The unique design helps reduce back/shoulder injuries and allows movement by people of small stature. Low pressure warning alarm is standard. Deck mounted hose reels and storage cabinets are just a few of the options available. ® SPECIFICATIONS FOR MODELS EAC-97ENB, EAC-97HENB, EAC-97PENB & EAC97PHENB Cart Dimensions Weight without Cylinders Frame Cylinder Straps Wheels/Casters Whip Assemblies Bleeder Valves Check Valves Warning Alarm Primary Regulator Pressure (Model EAC-97ENB & EAC-97PENB) Primary Regulator Pressure (Model EAC-97HENB & EAC97PHENB) Primary Regulator Flow Rate Relief Valve Air Distribution Transportation Ergo Design 32"W x 55"H x 38¼" D (81cm W x 140cm H x 97cm D) 250 lbs (114 kg) Steel Powder Coated Four (4) adjustable straps to accommodate different size cylinders Standard: 16" semi-pneumatic (front) 6" soft tread swivel casters with brake (rear) Optional: 16" pneumatic (front) 10" pneumatic casters with brake (rear) Thermo plastic 5000psi (345 bar) rated 4:1 safety factor Allows depressurization of hand tight nut before cylinder removal.

Push the handle up and forward to situate the cart in an upright position. Reinstall the clevis pin. Step 2) Install, arrange and index the air cylinders so that the valve outlets are facing away from the control panel. Secure cylinders by tightening the straps at the buckle and mating the velcro sections. Step 3) Model EAC-97HENB & EAC-97PHENB: Install CGA-347 hand tight nuts on the cylinder valves, and tighten. Insure both bleeder valves are closed by turning fully clockwise. Model EAC-97ENB & EAC97PENB: Install CGA-346 wrench tight nuts on the cylinder valves, and tighten. Step 4) Place the “on/off” toggle switch to the “on” position. The lights and alarms should should. Note: The alarm preset to sound at approximately 500psi (35 bar) descending pressure. If alarms do not activate, replace the 9-volt batteries. Step 5) LOW PRESSURE ALARM TEST Make sure the bleeder valves are closed; open one cylinder: a. At this time the alarm should shut off when system pressure reaches 500psi (35bar) or greater. b. Check the cylinder pressure on the high pressure gauge. c. Set required respirator pressure with the regulator control knob d. Close the cylinder valve and slowly bleed off pressure through one of the respirator outlets. e. The low pressure alarm should sound and the light should come on at approximatly 500psi (35 bar). f. Open the other cylinder and check its pressure on the high pressure gauge. Step 6) Couple respirators and lengths of hoses to the manifold, and readjust regulator control knob if necessary. The system is now operational. When a cylinder in use has been depleted to approximately 500psi (35 bar), the low pressure warning alarm will sound, indicating that the cylinder needs to be replaced. Optional) A variety of hose reel options are available. If the lower reel is to be used, open the valve located near the inlet. This will pressurize the hose reel. To change a cylinder while the cart is still in use: a. Open the second cylinder and note the gauge pressure to assure that the cylinder is full. b. Close the drained cylinder and open the bleeder valve (high pressure version) on the whip to relieve the remaining pressure on the hand tight nut. c. The system's check valves will prevent back flow from the other cylinder in use d. Replace or fill the drained cylinder and reinstall connecting whip. -5- SETUP FOR MODELS EAC-97ENB, EAC-97HENB, EAC-97PENB & EAC97PHENB -6- SPECIFICATIONS FOR MODELS EAC-97NB, EAC-97HNB, EAC-97PTNB, & EAC-97PHNB Cart Dimensions Weight without Cylinders Frame Cylinder Straps Wheels/Casters Whip Assemblies Bleeder Valves Check Valves 32"W x 55"H x 38¼" D (81cm W x 140cm H x 97cm D) 250 lbs (114 kg) Steel Powder Coated Four (4) adjustable straps to accommodate different size cylinders Standard: 16" semi-pneumatic (front) 6" soft tread swivel casters with brake (rear) Optional: 16" pneumatic (front) 10" pneumatic casters with brake (rear) Thermo plastic 5000psi (345 bar) rated 4:1 safety factor Allows depressurization of hand tight nut before cylinder removal.

Step 2) Install, arrange and index the air cylinders so that the valve outlets are facing away from the control panel. Secure cylinders by tightening the straps at the buckle and mating the velcro sections. Step 3) Model EAC-97HNB: Install CGA-347 hand tight nuts on the cylinder valves, and tighten. Insure both bleeder valves are closed by turning fully clockwise. Model EAC-97NB: Install CGA-346 wrench tight nuts on the cylinder valves, and tighten. Step 4) Open one cylinder. At this time the low pressure warning alarm will sound, until it sets itself at approximately 1000psi (69 bar). Check reading on gauge to verify that it is full. Close the cylinder. Step 5) Set required respirator pressure with the regulator control knob, and bleed pressure by partially engaging a male plug into one of the respirator fittings. This despressurizes the manifold, and simulates low cylinder pressure. The low pressure warning alarm should sound at approximately 500psi (35 bar). Step 6) Open the second cylinder. At this time the low pressure warning alarm will resound until it sets itself at approximately 1000psi (69bar). Check reading on gauge to verify that it is full. Step 7) Couple respirators and lengths of hoses to the manifold, and readjust regulator control knob if necessary. The system is now operational. When a cylinder in use has been depleted to approximately 500psi (35 bar), the low pressure warning alarm will sound, indicating that the cylinder needs to be replaced. Optional) A variety of hose reel options are available. If the lower reel is to be used, open the valve located near the inlet. This will pressurize the hose reel. To change a cylinder while the ERGO-AIR® CART is still in use: 1. Open second cylinder and note the gauge pressure to assure that it is full. 2. Close the drained cylinder. 3. Model EAC-97HNB & EAC-97PHNB: Open the bleeder valve of the drained cylinder. Remove CGA-347 hand tight nut. Replace with full cylinder. Reinstall connect whip. Close bleeder valve. Model EAC-97NB & EAC-97PTNB: Loosen CGA-346 wrench tight nut to relieve pressure. Replace with a full cylinder. Reinstall connect whip. Note: The system is equipped with check valves that will prevent back flow from the other cylinder in use. -9- SETUP FOR MODELS EAC-97NB, EAC-97HNB, EAC-97PTNB, & EAC-97PHNB -10- HIGH PRESSURE AIRLINE GENERAL MAINTENANCE & INSPECTION FOR ALL MODELS Monthly 1. Check regulators, gauges, and valves for external leakage. 2. Inspect cylinder valves for proper closure. 3. Check cylinder pigtails for cleanliness, flexibility, wear, leakage, blisters on hose, thread damage, and O-rings on CGA fittings. Replace damaged items immediately. Annually 1. Check relief valve’s pressure setting. 2. Check regulator function by opening and closing regulator valve knob fully. Every 4 years 1. Replace all flexible pigtails. SHUTDOWN FOR ALL MODELS Make sure all personnel have egressed the hazardous area and have disconnected from the breathing air system. 1. Close cylinder valves. 2. Depressurize manifold pressure by partially engaging male plug into one of the respirator fittings. 3. Close the regulator by turning the control knob counterclockwise. 4. Reinstall dust caps. 5. Remove connections from cylinders. Reinstall cylinder valve covers (if applicable). 6. If transportation of cart is required, remove clevis pin, place foot on base and pull handle until movement stops. Replace clevis pin. -11- Warranty Disclaimer Air Systems’ manufactured equipment is warranted to the original user against defects in workmanship or materials under normal use for one year after date of purchase.
